| Designed specifically for building, plant and facility maintenance & energy management, this course is designed for anyone who needs to understand basic operation, maintenance and troubleshooting of air conditioning and refrigeration systems in order to improve efficiencies and uptime at their industrial plants and large building facilities. Students can attend one, or both days of this two day seminar.
DAY 1 - PRINCIPLES, COMPONENTS & SYSTEMS
In Day 1 of this seminar, students are provided a broad introduction to Air Conditioning and Refrigeration - a great overview for apprentice technicians, multi-craft trades people, building managers, or anyone who wants to understand the general principles and concepts of A/C and Refrigeration. In addition to understanding the general principles, students will learn about the primary components and accessories used in air conditioning systems, how they work, and where and how these components and accessories are used in HVAC&R systems. Providing the student a well-rounded introduction to Air Conditioning and Refrigeration is the primary goal for Day 1. Discussions about refrigerants & oils, and accompanying regulatory laws will also be included in this first day.
